Where can I find a public weighbridge in Canberra?

I want to weigh my car, camper trailer and towball weight so I need to go over a weighbridge 3 times

I’d assume Mugga Lane would be too busy to do this comfortably, and I went to one in Hume that was on Google which appeared closed when I went there (during business hours). Can’t find anything on the TAMS website except how much it will cost to get a certificate, if you can find a weighbridge, but there you’re on your own.

Me too – I got my Magna weighed to prove to TAMS that it weighed the handbook weight, not the arbitrary amount that the rego mechanic (without a weighbridge) wrote on the form – taking it back below 1504kg and getting myself a $130 refund!!
